1. Will Hillary Clinton be too weak on climate change?

Clinton_82a8efb1-4abb-41ab-ab60-22fbbcb08b78-1020x612_500

Campaign chair John Podesta tweeted:

Helping working families succeed, building small businesses, tackling climate change & clean energy. Top of the agenda.

Yet she herself has mentioned it only obliquely since announcing that she’s running. From the past we have this:

At the National Clean Energy Summit in September of last year, in her first major domestic policy address since stepping down from the state department, Clinton described global warming as “the most consequential, urgent, sweeping collection of challenges we face as a nation and a world”.

1. Closing down dirty power


From Climate Code Red
, a recent Oxford University report:

identified the most-polluting, least-efficient and oldest “sub-critical” coal-fired power stations. It found 89% of Australia’s coal power station fleet is sub-critical, “by far” the most carbon-intensive sub-critical fleet in world.

The International Energy Association, within a framework that itself is probably inadequate, says that one in four sub-critical power stations should close within five years. Hence 22% of our power stations should close within five years if we are to do our part. Continue reading Climate clippings 135

1. Abbott’s energy white paper focuses on fossil fuel favourites

We should take a longer look at the Abbott government’s energy white paper, but from what Giles Parkinson says it would be a waste of time. As expected it ignores climate change and sees our future based on fossil fuels. Here’s Tones peering into our energy future:

The world will pass him by!

2. Solar news

RenewEconomy was a flood of articles about solar.

Sophie Vorrath:

A company based in the world’s largest oil exporting nation, Saudi Arabia, has become the new owner of Australia’s second-largest solar plant – the under-construction 72MW Moree PV project – after buying Spanish solar developer Fotowatio Renewable Ventures (FRV) and its 3.8GW global development pipeline.

Abdul Latif Jameel Energy and Environmental Services – a conglomerate that also has a base in the United Arab Emirates – announced its purchase of FRV on Wednesday, describing it as a major development of its energy business, and part of its on-going strategy to be the Gulf’s largest solar power plant developer.

Giles Parkinson says the prospects for big solar in WA are bright.

James Mandel and Leia Guccione take a look at a Rocky Mountain Institute report that analyzes how grid-connected solar-plus-battery systems will become cost competitive with traditional retail electric service and why it matters to financiers, regulators, utilities, and other electricity system stakeholders.

Paul McArdle reports on the benefits of tracking systems in solar PV from a seminar hosted by the UQ Energy Initiative and the Global Change Institute.

And more, as the Abbottistas fade into irrelevance, except that they are presently running (ruining?) the country.

3. Aluminium battery charges in one minute

US scientists say they have invented a cheap, long-lasting and flexible battery made of aluminium for use in smartphones that can be charged in as little as one minute.

The researchers, who detailed their discovery in the journal Nature, said the new aluminium-ion battery had the potential to replace lithium-ion batteries, used in millions of laptops and mobile phones.

Besides recharging much faster, the new aluminium battery is safer than existing lithium-ion batteries, which occasionally burst into flames, they added.

While lithium-ion batteries last about 1,000 cycles, the new aluminium battery was able to continue after more than 7,500 cycles without loss of capacity. It also can be bent or folded.

Larger aluminium batteries could also be used to store renewable energy on the electrical grid, Professor Dai said.

Meanwhile the US market for energy storage management systems, that is the software suites designed to increase the operating efficiency and overall value of energy storage, will grow tenfold between 2014 and 2019.

5. French banks rule out funding Galilee basin coal project

France’s three biggest banks have ruled out funding the controversial multi-billion dollar Galilee basin coal mining, rail and port development in Queensland. Eleven major international lenders have now publically stated that they won’t finance the $16.5 billion dollar project and one analyst says more delays could see the Indian company behind the project ultimately scrap the development.

6. Rising sea levels to force the largest exodus in history

Scientists calculate that within the next three decades a substantial area along the Bay of Bengal, a region of delta approximately 200 delta islands in India and Bangladesh called the Sundarbans, will be underwater due to climate change and rising sea levels. If that happens, the millions of people living there now will be forced to abandon their homes and lands, making their displacement the largest exodus in modern history.

Estimates predict that the region will be underwater within the next 10-25 years, forcing 8 million Bangladeshis and 5 million Indians inland.

That makes 13 million displaced. Other large movements cited include 10 million during the 1947 India-Pakistan partition and 7 million African Americans move from the southern states northward during the period 1916-1970. The one he missed was the movement of Germans from Eastern Europe towards the end and after World War II. Tony Judt reckons 13 million.

7. Contrarian climate scientists

Dana Nuccitelli reviews an interview with top contrarian climate scientists Roy Spencer and John Christy. You can read his analysis of their flawed thinking and erratic statements. I’d like to pull out three points.

First, John Cook et al’s survey that established the 97% consensus in the peer-reviewed literature on human-caused global warming does not categorise the 3% as complete denialists. The 3% includes papers by scientists, such as Spencer and Christy, who minimise human influence on global warming. Complete denialists amongst climate scientists are rare if they exist at all.

Second, the American Meteorological Society (AMS) and Yale University conducted a survey of meteorologists in relation to climate science and global warming. Only 13 percent of survey participants described climate as their field of expertise. I was surprised at how low the number is.

Third, on the cost of renewables:

Experts in these fields who have published research on the subject have found that fossil fuels are incredibly expensive, when we account for all of their costs. For example, one recent study conservatively estimated that including pollution costs, coal is about 4 times more expensive than wind and 3 times more expensive than solar energy in the USA today.

Global temperatures may be about to jump

Joe Romm at Climate Progress comments on recent research that suggests a significant increase in global temperatures may be imminent.

‘Significant’ here means two- or three-tenths-of-a-degree Celsius, which compares to the 0.16°C/decade average seen in this graph from NASA:

NASAwarmingTrend-cropped_600

Clearly in this graph there was a jump in the temperature around 1998, then a period of consolidation of near record temperatures or small increases in the temperature. All the years from 2001 on were hotter than 1997.

Kevin Trenberth explains that most of the additional warmth (over 90%) goes into the ocean and global increases tend to happen towards the end of an El Niño event, while La Niñas tend to be cooler. This pattern of El Niños and La Niñas (ENSO) which last 6 to 18 months is superimposed on the pattern of PDOs (Pacific Decadal Oscillations) which can last a decade or more. The importance of the PDO was outlined in the post Explaining the pause that wasn’t last December.

The pattern of PDOs is shown in this graph:

Pacific-Decadal-Oscillation-3-15_600

The 1998 jump came with the super El Niño in 1998 at the end of an extended period of positive PDO, from 1992 and 1998. Now we are entering an El Niño at a time when the PDO has turned strongly positive.

Romm interviewed Kevin Trenberth:

I interviewed Trenberth this week, and he told me that he thinks “a jump is imminent.” When I asked whether he considers that “likely,” he answered, “I am going to say yes. Somewhat cautiously because this is sticking my neck out.”

What is not said here is that the current El Niño is a weak one and may not have much effect on the weather. Trenberth thinks the PDO has the greater effect, which is then modulated by ENSO. Given the shape of the PDO over the last 15 years, the current El Niño might be like pulling the cork on a bottle of fizz.

1. Mt Everest’s poo problem

Every year climbers of Mt Everest leave behind 26,500 pounds of poo. I make that about 12 tonnes.

Sherpas pick it up, bring it down in blue barrels, dig a hole and dump it. Now the proposal is to build an anaerobic digester in a small village near Everest’s base to create biogas to produce power. Apparently human poo is not the best, but it works.

2. Arctic sea ice record

I think it’s time to call it. The Arctic sea ice winter maximum is the lowest on record. This graph shows 2015 ice against the previous record of 2011 and the 1981-2010 average:

sea ice_Feb 25_cropped_600

Also the maximum extent was reached on February 25, the second earliest on record.

According to a recent survey, thinning has been quite dramatic:

… annual mean ice thickness has decreased from 3.59 meters [11.8 feet] in 1975 to 1.25 m [4.1 feet] in 2012, a 65% reduction. This is nearly double the 36% decline reported by an earlier study….

In September the mean ice thickness has declined from 3.01 to 0.44 m [from 9.9 to 1.4 feet!], an 85 % decline.

Climate Central has a graphic showing the loss of ‘old’ ice. In 1987 it used to be 26% of the ice pack, now it’s down to 10%.

Polar bears will struggle to adapt.

3. Shell looks to drill in Arctic

Shell hopes to drill in the Chukchi Sea in the Arctic this summer. It looks as though Obama’s Department of the Interior will allow it, even though an Environmental Impact Report released by the Bureau of Ocean Energy Management (BOEM) noted a 75% chance of one or more large spills occurring under the current plan. In 1989 the Exxon Valdez disaster spilled nearly 11 million gallons of crude oil into the Alaskan Gulf, polluting over 1300 miles of coastline. It is estimated that only 14% of the oil was cleaned up.

By comparison BP’s Deepwater Horizon oil rig spilled 168 million gallons of oil into the Gulf of Mexico off the Louisiana coast.

Yet Obama himself stresses the need to move early on climate change. More than half of Republican politicians deny or question the science. Voter pressue will change that eventually.

A recent Stanford University poll found that two-thirds of voters were more likely to vote for a candidate that campaigned on a platform of fighting climate change, and were less likely to vote for a candidate that outright denies climate change.

4. Land, ocean carbon sinks are weakening

We are destroying nature’s ability to help us stave off catastrophic climate change. That’s the bombshell conclusion of an under-reported 2014 study, “The declining uptake rate of atmospheric CO2 by land and ocean sinks,”…

Based on actual observations and measurements, the world’s top carbon-cycle experts have determined that the land and ocean are becoming steadily less effective at removing excess carbon dioxide from the atmosphere. This makes it more urgent for us to start cutting carbon pollution ASAP, since it will become progressively harder and harder for us to do so effectively in the coming decades.

Joe Romm calls the study “one of the most consequential recent findings by climatologists”

More than half of emissions are currently absorbed by land and ocean-based carbon sinks. Increasingly these emissions will stay in the air.

5. Reasons the Australian solar market is so interesting

Clean Technica has found 7 reasons the Australian solar market is so interesting republished at RenewEconomy.

One reason is that we have so much sunlight, as shown below:

solar-australia

However, most of us live in the more cloudy parts in big cities and along the south-east edge. A commenter pointed out that for insolation Ney York lies between Melbourne and Sydney.

A second reason is that we are enthusiastic about roof-top solar, with over 20% of houses now with panels installed.

A third is that, along with Germany, Italy and The Netherlands, we reached socket (aka grid) parity in 2013.

1. Accelerating ice loss from Antarctica shelves

Some ice shelves in Antarctica are thickening and some are thinning. The pattern between east and west is obvious from this image:

ice shelves_image-20150326-8713-1fyzwcb_600

When we sum up losses around Antarctica, we find that the change in volume of all the ice shelves was almost zero in the first decade of our record (1994-2003) but, on average, over 300 cubic kilometers per year were lost between 2003 and 2012.

According to the ABC story, some shelves lost almost 20% of their thickness.

Melting ice shelves does not itself cause sea level rise, but the shelves buttress land ice, which then becomes more mobile. The graph in the bottom corner of the image shows that East Antarctica is now also experiencing a net loss of ice from ice shelves.

2. Top polluters to set own limits virtually penalty free

ANU economist Frank Jotzo said the system is designed so no-one gets caught by it – a toothless tiger. Tony Wood of the Grattan Institute said the ideas proposed in the paper simply would not work. They were commenting on a Government consultation paper outlining “safeguards” to ensure the big polluters do not offset emissions saved through the Emission Reduction Fund (ERF), a flagship component of Direct Action.

Australia’s 140 top polluters will set their own limits for future pollution virtually penalty free, according to the Government’s latest Direct Action policy paper.

Companies subject to the safeguards will select a baseline, or limit, for future pollution.

That baseline will be set according to the highest peak of emissions from the past five years.

Just plain stoopid!

3. What’s going on in the North Atlantic?

Stefan Rahmstorf asks the question at RealClimate. There is a large patch in the North Atlantic which has cooled in the last century.

Rahmstorf_2015_1rc_600

Rahmstorf explains:

Our recent study (Rahmstorf et al. 2015) attributes this to a weakening of the Gulf Stream System, which is apparently unique in the last thousand years.

In fact during last winter, which was the warmest on record for the planet overall, this patch had the coldest temperatures on record.

Chief suspect has to be the increasing freshwater coming off Greenland. There will be consequences.

The consequences of a large reduction in ocean overturning would look nothing like the Hollywood film The Day After Tomorrow. But they would not be harmless either – e.g. for sea level (Levermann et al. 2005) particularly along the US east coast (Yin et al. 2009), marine ecosystems, fisheries and possibly even storminess in Europe (Woollings et al. 2012).

A complete breakdown of the current was given up to a 10% chance this century in the IPCC report. This may have been an underestimate.

4. Rapid Arctic warming is changing the Jetstream and the weather

Another study, also involving Rahmstorf, looks at changing atmospheric circulation patterns due to Arctic warming.

The Arctic is warming faster than lower latitudes. The Jetstream velocity depends on temperature difference, hence it is slowing. It is also more wavy and has a tendency to get stuck, so heat or cold persists over a large area. Ironically, there is less storminess. Storms transport water onto land and break up persistent weather patterns.

The jet stream that circles Earth’s north pole travels west to east. But when the jet stream interacts with a Rossby wave, as shown here, the winds can wander far north and south.

5. Brisbane EV charging technology takes on the world

Brisbane-based electric vehicle infrastructure company, Tritium, has done a deal to supply its award-winning Veefil DC fast charging stations to America’s ChargePoint company. ChargePoint has 21,000 EV chargers around the US.

The Australian-made stations will be installed on major routes across the country, including the express charging corridors on both the east and west coasts of the US that are being built as part of a recent deal between ChargePoint, Volkswagen and BMW.

The 50kW Veefil stations – which in the US will be called DC Fast stations and will be ChargePoint branded – are able to deliver up to 80 miles or 128 kilometers of charge in just 20 minutes, thus removing one of the key barriers to EV uptake: range anxiety.

1. Totten Glacier

In Climate clippings 124 I mentioned concerns about Totten Glacier in East Antarctica, which is actively melting. It’s now in the news again. Dr Tas van Ommen:

“We’re realising that the East Antarctic ice sheet’s probably not the sleeping giant that we thought or at least, the giant’s starting to twitch and we’re concerned,” he said.

This article has a map showing the size of the glacier catchment, more than double Victoria:

Totten_6326094-3x2-600

Essentially with East Antarctica on the move, estimations of sea level rise this century could be underdone. We simply don’t know.

2. Great Barrier Reef ‘saved’

The Federal and Queensland Governments have together released the final version of the long-term plan for the Great Barrier Reef.

The Reef 2050 Long-Term Sustainability Plan satisfies one of the key recommendations made by the United Nation’s World Heritage Committee and forms a key plank in the Governments’ bid to avoid the site being declared “in danger” by UNESCO.

The report warns climate change is the biggest long-term threat facing the reef, while the immediate pressures include water quality, which has declined due to nutrient and sediment runoff from agricultural production.

Previously, a draft version of the report was criticised by some scientists as being a plan for sustainable development rather than protecting and conserving the reef.

The Queensland Government also sought urgent changes to the draft, to include its $100 million election commitment to improve water quality.

These news items never mention ocean acidification. As I’ve repeatedly warned:

It has been shown that “preserving more than 10 per cent of coral reefs worldwide would require limiting warming to below +1.5°C (atmosphere–ocean general circulation models (AOGCMs) range: 1.3–1.8°C) relative to pre-industrial levels”.

3. France says new rooftops must go green

According to a new French law approved on Thursday, rooftops on new buildings in commercial zones across France must either be partially covered in plants or solar panels.

France has lagged behind other major European countries like Germany, Italy and Spain in solar power development. As of last summer, France had just over five gigawatts of photovoltaic capacity, accounting for around one percent of total energy consumption. Germany has nearly 40 GWs installed.

France has relied on nukes for 83% of its power.

4. Are the UK’s emissions really falling?

Traditional emissions accounting only considers the greenhouse gases generated within a country’s own borders. In other words, emissions produced in the UK are allocated to the UK. On this measure, UK emissions have fallen dramatically to around 25% below 1990 levels.

But when the source of emissions generated by products consumed within the UK are counted, emissions have only fallen by 7%. This is the pattern over time:

UK emissions_screen-shot-2015-03-19-at-144932_599x299

The UK’s production emissions have fallen fast (dark blue area), but imports have offset much of the gain (lighter blues, purples and grey area). Clearly things changed after the GFC in 2008.

5. Germany penalises dirty coal power

Germany plans to force operators of coal plants to curb production at their oldest and most-polluting power stations, as part of efforts to achieve its climate targets, senior government sources said yesterday. Under the measures, the government plans to allow coal plants to produce 7 million tonnes of carbon dioxide per gigawatt of installed capacity, but any produced above that level would be subject to a fine of 18 to 20 euros per ton.

6. Australia’s top ten emitters

Planet Oz takes a look at an ACF report on Australia’s top polluting companies. From the report here they are:

Top 10 polluters_cropped_600

Seven are energy companies, three are miners.

However, if you took the emissions generated from the products they produce, a very different picture would emerge. Rio, for example comes fourth with emissions of 18 million tonnes of CO2 last year. Yet Rio’s customers burning coal produce a further 129 million tonnes.

7. Climate change ‘exacerbated’ Cyclone Pam damage

That’s according to the Climate Council, (but see Item 8 below).

“Higher surface temperatures can mean that you have higher wind speed and more damaging rainfall,” Amanda McKenzie from the Council said.

“And what we saw in Vanuatu was in the lead-up to the cyclone, sea surface temperatures were well above average.”

Ms McKenzie said rising sea levels would multiply the damaging effects of cyclone storm surges.

Cyclone Pam, a category-5 storm with wind gusts reaching 300 km/h, struck Vanuatu on 13 March 2015 leaving twenty-four people dead, 100,000 people homeless and up to 70% of the nation’s 69,000 households damaged.

8. Cyclone Pam and Climate Change

Stefan Rahmstorf at RealClimate takes a look at whether climate change had an effect on Cyclone Pam.

My take is, quite possibly, but we can’t know for sure.

The basic problem is that the satellite record only goes back to around 1980, which is not long enough, and only in the North Atlantic are cyclones surveyed by aircraft and then only if they threaten populated regions within a few days.

A study by Kossin et al (2013) looked at the satellite data record from 1982 to 2009 and found an increase of 2.5 m/s per decade for high intensity events (Pam appears to have reached an intensity of around 75 m/s).

Other factors to look out for include the amount of rain delivered, changes in genesis locations and tracks, and diameters, all of which should be affected by climate change.

Haiyan and Pam, two of the most severe tropical cyclones on record, have struck the western Pacific in the past 16 months.

1. Polar bears – uncertain future

The Mail on Sunday recently declared the polar bear in good shape on the basis of the opinion of biologist Dr Susan Crockford, who says:

“On almost every measure, things are looking good for polar bears … It really is time for the doom and gloom about polar bears to stop.”

It turns out that Crockford’s expertise is the archaeology of dead dogs and the identification of animal remains, and receives funding from the Heartland Institute to spread disinformation about human agency in climate change.

Information, reliable or not, is difficult to come by. This is a snapshot of one estimate of how the polar bear is travelling:

Polar bears_screenshot-2015-03-04-154610_575x539

In nine of the 19 populations of polar bears information is deficient.

On their future the best estimate is:

To keep polar numbers relatively healthy, though still lower than today, scientists suggest global temperatures should not exceed 1.25 degrees Celsius above the 1980-1999 average.

2. Arctic sea ice is getting thinner faster than expected

Measuring the thickness of the Arctic sea ice sheet is not a simple matter. data from disparate sources has been brought together for the first time.

in the central part of the Arctic Ocean basin, sea ice has thinned by 65% since 1975. During September, when the ice reaches its annual minimum, ice thickness is down by a stunning 85%.

3. UK auctions for renewables

Contracts worth £315 million have been awarded to 27 renewable energy projects with a combined capacity of 2.1 gigawatts.

The majority of the 27 schemes are windfarms, including 15 onshore and two offshore schemes (the blue and green chunks below). The remaining contracts went to five solar farms (yellow) and five schemes that will burn or gasify waste to generate energy (black and grey).

UK_Screen Shot 2015-02-26 at 15.48.48_600

By peak capacity the outcome looks rather different:

UK_Screen Shot 2015-02-26 at 15.48.54_600

The auction was divided into two pots, with one pot reserved for “less established” technologies.

The big surprise was the prices, which were lower than expected.

4. Keystone XL pipeline bill vetoed

It’s important to note that the pipeline bill has been vetoed, not the pipeline.

Keystone is not dead. The bill was a political Tea party move to pre-empt State Department approval, which will now continue until a recommendation in made to John Kerry as Secretary of State.

Meanwhile Nebraska landowners are fighting a case in the courts. They claim state law giving TransCanada the right to drive the pipeline through their land under ’eminent domain’ is unconstitutional.

If the landowners succeed TransCanada does not have a route for the pipeline.

A longer post on the issue is here.

5. The IPCC reviews it’s processes

Every seven years the IPCC publishes three whopping reports followed by a Synthesis Report. Working Group 1 looks at the physical basis of climate change. Working Group 2 looks at impacts, adaptation and vulnerability. Working Group 3 looks at mitigation. Each of these whopping tomes has a Summary for Policy Makers of about 30 pages.

The main decision is that the program will continue with some minor modifications. They will try to link the second and third volumes more specifically to the first, while producing the whole series within about 18 months.

More special reports on specific issued will be produced during the interim years.

They will try to make the summaries for policy makers more readable.

6. NZ infestation of flat-earthers climate denialists

The Dominion Post is the newspaper of record for New Zealand’s capital city, Wellington. Last Friday it featured an opinion piece by high profile climate denialists Bob Carter and Bryan Leyland titled Hypothetical global warming: scepticism needed. Gareth Renownden at Hot topic calls it

a “Gish Gallop” of untruths, half-truths and misrepresentations — a piece so riddled with deliberate errors and gross misrepresentations that it beggars belief that any quality newspaper would give it space.

He then identifies 24 specific errors or misrepresentations.

7. EU adopts climate change targets for Paris conference

The EU formally adopted on Friday climate change targets for December’s Paris conference including a 40 percent cut in emissions by 2030, climate commissioner Miguel Arias Canete said.

The targets were agreed on by leaders of the 28 European Union member states at a summit in October, but the confirmed benchmarks have now been officially sent to the UN, Canete said.

The EU was the second after Switzerland to publish its submission.

In other EU news, the Commission is to spend €100 million on projects aimed at connecting energy networks across the continent.

8. El Niño finally arrives

El Niño has finally arrived at a time of the year when they usually decay. It’s weaker than usual and is unlikely to have much impact on world weather.

9. US weather conundrum

Last week I reported (Item 1) that the planet had just experienced the hottest 12 months, while it was freezing in eastern North America during January and February and into March.

Because winter includes December and December was mild, no state had a record low winter. In fact the East’s brutal cold was offset by record warmth in the West, which was caused by warmth in the Northern Pacific. The experts think this pushed the jet stream out of shape, bringing Arctic air further south in the east.

It seems the Northern Pacific warmth has now moved to the Central Pacific, causing the weak El Niño referred to above.

1. Hot and cold

My sister in Toronto tells us how cold it has been. She can’t remember the last time it reached -5°C.

Yet NASA finds that Feb 2014 to Jan 2015 was the hottest 12 months on record. The picture tells the story:

NASA1-15-550

2. Record megadroughts predicted

The American Southwest and the great Plains could experience the worst megadroughts in ancient and modern times.

According to the findings, future droughts in both regions will be more severe than even the hottest, driest megadroughts of the 12th and 13th centuries, which are believed to have contributed to the fall of ancient Native American civilizations that inhabited the Southwest, such as the Pueblo Indians.

Climate Central gives the odds.

The chances of a megadrought (lasting 35 years or longer) are up to 50%.

The odds of a decade-long drought are around 90%.

There’s also a 5-10 percent chance that parts of the region could see a state of “permanent” megadrought lasting 50 years or longer under the highest-warming scenario, a greenhouse gas emissions path we’re currently on.

3. New era of climate action and hope

Christiana Figueres reckons 2015 is going to be a transformational year in climate change action. She of course is the boss-person of the United Nations Framework Convention on Climate Change (UNFCCC) which is sponsoring the Paris talks in December.

Amongst other things she mentions the June Live Earth concerts initiated by Al Gore and Kevin Wall (reviving their 2007 effort) to be held in New York, South Africa, Australia, China, Brazil and Paris.

She also plugs the UNFCCC’s Momentum for Change initiative, including Lighthouse Activities.

4. UK parties in pact on climate change

David Cameron, Nick Clegg and Ed Miliband have agreed to work together to tackle climate change, as they warned it posed a threat to national security and economic prosperity.

In what might be seen as a surprising move in the run-up to the general election, the three party leaders have pledged to work “across party lines” to agree cuts to the UK’s carbon emissions.

They have also signed up to seeking a “fair, strong, legally binding” international climate deal, set to be negotiated in Paris at the end of the year, to limit global temperature rises to below 2C – the level beyond which “dangerous” climate change is expected.

And they pledged to move to a low-carbon economy, ending the use of coal without technology to capture and store its emissions for power generation. (Emphasis added)

5. Tesla’s fancy home battery

Tesla will start production in about six months, all going well.

“We are going to unveil the Tesla home battery, the consumer battery that would be for use in people’s houses or businesses fairly soon.”

“Some will be like the Model S pack: something flat, 5 inches off the wall, wall mounted, with a beautiful cover, an integrated bi-directional inverter, and plug and play.”

Thanks to Geoff Henderson who linked to this one recently at Saturday Salon. Yes, it could indeed be a game changer.

6. Laser ignition to replace spark plugs

A team at Princeton Optronics working on replacing conventional spark plugs with laser igniters has produced a running engine and they claim that replacing spark ignition with lasers could improve the efficiency of gasoline powered engines by 27%. Considering that the basic design of the spark plug hasn’t really changed in over a century, this would be a revolutionary step, frickin’ lasers or not.

Because the spark plug is located on the edge of the combustion chamber, not all of the fuel is combusted. Laser ignition can be directed to the centre of the chamber, or in fact to multiple parts of the chamber in extremely rapid succession. Ignition can also be more accurately timed in relation to the movement of the piston. The result is a more complete burn and greater fuel efficiency.

7. Climate oscillations and the global warming faux pause

Michael Mann posts on research he was conducted, with others, on multidecadal climate oscillations in the Pacific and the Atlantic Oceans. They found that the Pacific dominates and was the predominant cause of a slight slowing in predicted warming over the past decade-and-a-half or so.

It is possible that the downturn in the PMO [Pacific Multidecadal Oscillation] itself reflects a “dynamical response” of the climate to global warming. Indeed, I have suggested this possibility before. But the state-of-the-art climate model simulations analyzed in our current study suggest that this phenomenon is a manifestation of purely random, internal oscillations in the climate system.

This has implications for the future.

Given the pattern of past historical variation, this trend will likely reverse with internal variability, instead adding to anthropogenic warming in the coming decades.

The “false pause” may simply have been a cause for false complacency, when it comes to averting dangerous climate change.

1. Queensland’s minister for the reef

Premier Palaszczuk’s new ministry contained some surprises, including the appointment of Steven Miles as Minister for the Great Barrier Reef. His full handle is Minister for Environment and Heritage Protection, Minister for National Parks and the Great Barrier Reef.

According to the WWF, Minister Miles will be responsible for delivering ALP environmental commitments including: a ban on dumping dredge spoil in the Great Barrier Reef World Heritage Area; an 80 per cent reduction in pollution run-off into the Reef by 2025; and the reinstatement of key legal safeguards.

2. Japan now has more EV chargers than petrol stations

The number of EV charging points in Japan, including fast-chargers and those installed in homes, has reached 40,000, surpassing the nation’s 34,000 gas stations, a new report has found.

The surprising figures were reported last week by Japanese auto giant Nissan, whose fully electric car, the Leaf, has been one of the world’s big EV success stories, selling 160,000 cars globally since its 2011 launch date.

Mainly in Japan, the US and Europe.

It should be noted that some of the charging stations are in private homes. Also petrol stations have multiple pumps, not reflected in the figures.

Tesla has its own network of (solar powered) charging stations in the US – and has plans to build versions of this supercharge network in China, Europe and Australia.

In Australia, local fast-charge tech company, Tritium, installed its first public Veefil EV charger in Brisbane at a BMW dealership in Fortitude Valley – the first of a planned “electric super highway” of fast chargers along the east coast.

3. Temperature records vs trends

Gavin Schmidt, who has succeeded James Hansen as head of NASA GISS, has some Thoughts on 2014 and ongoing temperature trends. The shorter Schmidt is that while individual records grab the headlines, they don’t matter nearly as much as the underlying trend. This graph shows the overall trend in relation to El Niño and La Niña and years:

graph_gis_2014-1_600

The blue bars represent La Niña years, the orange El Niño and the grey neutral years. 2014 is bang on trend, but only marginally higher than 2005 and 2010. Yet it is grey to their orange.

Schmidt doesn’t mention this, but while 2014 was neutral it did feature anomalous warming in the northern Pacific, rather than the eastern equatorial Pacific warming associated with El Niños. This warming is said to have some of the same climatic effects as El Niño. Perhaps we need a new category with a fancy name.

4. Climate sensitivity conundrums

The term is “equilibrium climate sensitivity” (ECS). It represents “the global surface temperature change anticipated as a result of doubling atmospheric carbon dioxide concentrations.” John Fasullo has done a post on the current challenges and constraints in relation to the concept. It’s technical and I find it a bit boring, but ECS is an absolutely central concept to climate change discourse.

The basic problem is that the IPCC broadened the uncertainty range at the lower end from 2-4.5°C in IPCC4 to 1.5-4.5°C in IPCC5. The likely midpoint is still 3°C.

Fasullo has a lot of complex argument about the constraints arising from observations and models. What I think it comes down to is this.

The cut-off date for published papers for IPCC5 was July 2012. Prior to that date there had been several papers suggesting uncertainty at the lower end. Now the literature has swung back the other way. There was also the ‘warming pause’, which for a while back there was deemed by some to be real.

Fasullo makes it clear that the calculations are based largely on short-term effects. In Climate clippings 125 I referred to a David Spratt article which refers to the work of Hansen, Tripati and others which put longer term ECS at 4.5°C or more. And part of the point of the Michael Mann article was that we are starting to get into the longer term feedback zone.

I think they should all go back and read Hansen et al Earth’s Energy Imbalance and Implications (2011, I think) pages 4-18. The table on p17 gives ECS at 8°C or more, depending on certain definitions and circumstances.

5. Origin Energy to build Australia’s biggest rooftop solar array

Origin Energy and Zen Energy Systems are to build a 3MW solar system on the rooftop of the old Mitsubishi factory in Tonsley, Adelaide, in what will be the largest rooftop solar array in the country.

The awarding of the contracts was announced by the South Australian government this week. The intention to build the array was first announced late last year.

Origin Energy will own the rooftop array and sell the output to the tenants of the Tonsley high tech centre…, under a power purchase agreement that it is looking at replicating elsewhere in the country.

Here’s an artist’s impression of the site:

6. Origin shifts retail focus to rooftop solar and battery storage

Origin Energy has provided further details of its impending major push into the domestic solar market, saying that it expects rooftop solar to grow five-fold over the next 15 years, and battery storage will also emerge.

The Tonsley centre initiative is one example of this company reorientation. Seems AGL is looking to follow suit.

1. New research reveals extreme oxygen loss in oceans during past climate change

New research published this week reveals that vast stretches of the ocean interior abruptly lost oxygen during the transition out of the last ice age that occurred 17,000–10,000 years ago.

If that happened as a result of the relatively gentle forcing caused by changes in the Earth’s orbit, imagine what is possible now!

Like most of the life on the planet, the large majority of marine organisms need oxygen to live. Most marine life, from salmon, crabs, to shellfish, respires oxygen and many forms are intolerant of low oxygen seawater.

So-called ‘dead zones’ do contain life comprised of worms, bacteria, specialized urchins and bivalves, and other extremophiles, just not the kind of tucker we like to eat.

2. India ‘walking the talk’ on climate change

India is one country a bit allergic to discussing agriculture and climate pollution. They worry about feeding the millions. They also got a serve from Obama when he was there:

During a visit to New Delhi last month, Obama warned that the world does not “stand a chance against climate change” unless developing countries such as India reduce their dependence on fossil fuels.

India, as usual, is impervious to pressure, but the environment minister reckons they are doing their bit. New prime minister Narendra Modi is keen on renewable energy:

Since coming to power in May, Modi has pledged to increase India’s renewable energy in a bid to lower coal use and bring electricity to more than 300 million poor people currently without power.

Modi, who built up a solar industry in Gujarat state when he was chief minister, has set a target for India to have 100 gigawatts of solar capacity by 2022.

3. Abbott’s decline attributed to G20 Obama snub and climate change

On Newspoll Abbott’s net approval rating is now -44 (68% disapprove, 24% approve of how he is doing his job). Jason Wison says:

After a polling mini-recovery of sorts for Abbott between July and September, November – the month of the G20 and Obama’s address – marked a turning-point. Between September and November, Abbott’s always-poor net satisfaction ratings had improved and stabilised a little; from November they declined rapidly to where they are today. In some polls, Abbott now has more than half the voters saying that he should resign. November was also the month in which Bill Shorten decisively overcame Abbott as preferred prime minister, and Shorten’s lead is now wider than ever.

Wilson reminds us that Abbott refused to accept President Obama’s request to put climate change on the G20 agenda. Obama’s response was to kick off his stay with an address at the University of Queensland embarrassing Abbott with his references to Australia and climate change.

4. Maurice Newman wrongly claimed a UK charity had blamed the deaths of elderly people on renewable energy policies

Maurice Newman is of course Tony Abbott’s top science advisor. Graham Readfearn investigated his claim and found:

Newman is not only misrepresenting the charity’s position, he appears to be making up positions that the charity simply does not hold.

Also:

between 2004 and 2011 the average annual energy bill in the UK went up from £610 to £970.

Only £30 of that £360 increase was due to costs related to low-carbon power generation.

Most of the increase, the analysis said, was down to higher gas prices and network costs (maintaining poles and wires).

In my view, Newman’s attempt to pin the blame for the deaths of UK pensioners on renewable energy policies is either disgustingly dishonest or pathetically sloppy.

In the rest of the article Readfearn gives an explainer on how world surface temperature is measured.

5. Miocene temperatures

This Skeptical Science post gives a detailed account of what happened 14 to 17 million years ago in the “Mid Miocene Climate Optimum” (MMCO):

The MMCO was ushered in by CO2 levels jumping abruptly from around 400ppm to 500ppm, with global temperatures warming by about 4°C and sea levels rising about 40m (130 feet) as the Antarctic ice sheet declined substantially and suddenly.

Over the succeeding 2-3 million years Antarctic ice fluctuated dynamically in response to orbital wobbles, showing it was balanced on a knife-edge between a world with little ice and a world with substantial ice caps. Ice-free parts of Antarctica were rain-drenched and supported lush vegetation, while Arctic land was covered by temperate forests. Parts of the planet that had been arid before the MMCO rapidly re-greened and reforested (eg Patagonia).

This graph plots temperature and CO2:

Miocene_cropped_600

There were some differences between then and now. The Isthmus of Panama had not closed, for example. The warming happened on a warmer base.

Our warming is about 1000 times faster, giving less time for ecosystems to adapt. This is problematic for ocean acidification inter alia.
